FEEDING HOPPER FOR BOX MACHINES.

Application iled March 29, 1922. Serial N'o. 547,939.

To all whom t may cof/wcm:

Be it known that I, SHELTON J. GUNN, a citizen of the United States,residing at Gunntown, in the county of Levy and State of Florida, haveinvented certain new and useful Improvements in Feeding Hoppers for BoxMachines, of which the'following is a specification.

This invention relates to feeding hoppers for box machines.

The object of the invention is to provide a hopper adapted to feed aplurality of strips or boards consecutively to a reciprocating carriagewhich in turn feeds the boards through the machine for differentoperations.

Figure 1 is a partial sidefelevation of the machine with the hopperattached.

Fig. 2 is an end View of the machine and hopper.

The numeral 1 indicates the main frame of the machine supported uponsuitable legs 2. The numeral 3 indicates the parallel side barsconstituting a reciprocating carriage which is supported upon suitableguide ways l-t supported upon a transverse member 5 arranged beneath themain frame.

Arranged above the main frame is a hopper preferably consisting of asubstantially 30 rectangular frame 6 supported by rackets 7 above themain frame. Extending vertically from the rctano'ular frame are aplurality of guide members S forming the sides and ends of the hopperpreferably being flared outwardly at their upper ends to facilitateloading the hopper. Pivoted as at 9 to the rectangular frame 6 is a pairof presser arms 10-10 having their inner ends l1 bent inwardly over the@strips of the material. A arranged in the hopper. The outer ends 12 ofthe arms 10H10 are connected by links i3- 13 to afoot actuating lever14- pivotcd as at 15 to a stationary member 16. A spring 17 serves tohold the foot actuating member normally in the upper position exerting adownward pressure upon the arms 10-10 pressing the material downwardlyupon the main frame. Dogs 1S carried by the reciprocating carriage serveto withdraw a strip from beneath the pile at predetermined intervals,the arms 10-10 forcing the material downwardly as they strips arewithdrawn fromthe under side of the stack.

Vhen refilling the hopper the foot lever 14: is pressed downwardlycausing the arms 10-10 to swing outwardly past the edge of the hopperafter which the hopper may be readily filled.

It will thus be seen that I have constructed a feeding hopper which issimple in construction and effective in operation, consist-v y hopper, afoot lever, links connectinor said foot lever and presser arms forextending a downwardly pressure upon said pivoted presser arms.

2. A feed hopper comprising a main frame, a substantially rectangularframe mounted upon said main frame, a horizontally movable carriagemounted within said main frame, presser arms pivotally connected to saidframe having their outer free ends bent inwardly into the feed hopper,and means exerting a downwardly pressure upon said arms whereby thecontents of said hopper are held in contact with said horizontallymovable carriag 3. A feed hopper comprising a substantially rectangularframe, guides extending vertically from the frame, supporting membersarranged beneath the frame adapted to support the frame and forming abottom therefor, arms pivotally connected to the frame having inwardlyprojecting portions extending' into said hopper and means exerting adownwardly pressure upon said arms.

4. A feed hopper comprising a substantially rectangular frame,supporting members arranged beneath the frame, presser arms pivotallyconnected to said frame having their inner ends projecting inwardly intothe feed hopper, a foot actuated lever connected by suitable links tosaid arms, a spring connected to said foot lever for exerting adownwardly pressure upon said pivoted arms.

In testimony whereof I affix my signature.

SHELTON J. GUNN.
